alt-tab icon list in gnome and metacity?
 

Hi,

Can anyone provide a reference or explain how the icons to the alt-tab list is populated? I would like to specify some icons for some programs that do not have icons, e.g. xterm. I'm using Ubuntu 11.04 with gnome 2 (ubuntu classic) and metacity as the window manager. I googled but did not find anything.

I did see this thread that mentions /usr/share/pixmap/, but I "cp gnome-terminal.xpm xterm.xpm" but the icon was not populated in the alt-tab icon list (even after a logout/login). I do see that the icon is populated when I added the xterm command to the Program Menu. Please help with the alt-tab list, thanks!
